O&M Management FAQ
A date parameter is named "Start 1". Why does a card report "Query statement parsing error" when I add it?
Cause: Global parameter naming rules do not allow spaces. A parameter with spaces cannot be used properly.
Solution: Use an underscore instead of a space in the parameter name. For example, change "Start 1" to "Start_1".
Why does login show that the page does not exist, or return 404?
Cause: The user opened a link to a page they do not have permission to access.
Solution:
1) Log in from the BI homepage URL without a path suffix, such as app.guandata.com.
2) If the error has already appeared, click a top navigation button such as Dashboard or Data Center to switch to a page you can access. The left navigation bar will then recover.
Can a child user group be moved to the root directory?
Answer: No. A child user group cannot be moved to the root directory. It can only be moved under another user group.
What is the whitelist address for the SaaS environment? If the database requires a whitelist before access, add the SaaS environment IP.
Answer: IP: 52.131.237.184 (app.guandata.com)
5. Our company already has many reports. If we purchase Guandata for self-service analysis, what should we do with the existing reports? Do we need to rebuild all of them?
Answer: Currently, reports cannot be converted to Guandata reports with one click. You can embed them into a unified enterprise portal through an iframe, or use an external link card on a Guandata page to embed report pages from other third-party systems.
How can I count Guandata platform usage over a period of time?
Answer: Use Admin Settings - Task Management to view recent task status on the Guandata platform. Use the BI User Behavior Analysis page and the datasets in the Built-in-Dataset folder to count BI usage across all users. Use Nine-grid - Cloud Inspection to view recent system health.
After logging in to Guandata, will the system automatically log out if I do not operate or refresh the page for a long time?
Answer: Yes. The system automatically logs out after 24 hours.
Why can a general user who owns a dataset grant user permissions but not user group permissions?
Cause: In Admin Settings - Permission Management - Advanced Settings - Group Permission Control, the "Allow users to assign permissions to user groups" switch is disabled.
Solution: Enable the "Allow users to assign permissions to user groups" switch.
9. Which has higher priority: LDAP associations created by account synchronization or LDAP associations created manually?
Answer: There is no priority difference. The latest run time takes effect.
At what threshold are server resource alerts pushed?
Answer: CPU, memory, and disk alerts are triggered at 75%. To adjust the threshold, contact Guandata staff to operate from the server side.
If a user belongs to two user groups and both groups have default pages, which default page opens for the user?
Answer: When a user belongs to multiple user groups, such as A and B, the system compares the modification time of the default pages for user groups A and B.
The most recently modified group default page takes effect.
Can I shut down the server without stopping BI services?
Answer: BI allows the server to shut down without stopping services first, and BI services can start automatically after the server starts. However, to follow standard operations and avoid data loss, stop BI services according to the Startup and Shutdown Manual before shutting down the server.
What happens to task status when restarting the ETL jobserver or restarting BI on the server?
Answer: In Admin Settings -- Service Management, restarting the ETL jobserver can forcibly cancel all running tasks. Restarting BI on the server, performed by O&M staff, forcibly cancels all running and queued tasks. Both operations briefly affect users.
Why does the Resource Monitoring page show memory usage of 80% or higher when no tasks are running?
Answer: The BI system mainly uses Spark for computation, so it pre-allocates memory for Spark. To improve response speed, the system does not release this memory after each use. After a machine runs for some time, memory usage usually stabilizes at 80%-90% of total memory. This is expected and normal. If memory usage exceeds 90%, contact Guandata promptly to adjust memory allocation.
Cloud Inspection: If multiple domains are deployed on one server, will inspection results differ when only one domain is inspected?
Answer: Some data is not divided by domain, such as server-level data including CPU and memory. This type of data counts only the server and ignores domains. However, system usage metrics such as ETL and datasets are divided by domain.
After I import and then delete a file dataset, it still shows as running in Task Management. How do I cancel it?
Import and export operations consume server resources and cannot be canceled from Task Management. After you delete the dataset, the task can no longer be canceled and will keep running until it fails. When uploading large files, upload them during off-peak hours. If the upload does not succeed for a long time, click Cancel first, then delete it. Do not delete it directly.
What is the detailed logic of task priority?
Priority does not take effect when tasks are not queued. When tasks are queued, the system first checks priority and then time. If tasks have the same priority, the earlier task runs first. For example, when many tasks are queued, the task with the highest priority runs next.
How do I limit an account to logging in on only one device at a time?
Go to Admin Settings - System Management - Login Settings and make sure the single sign-on setting is enabled. Single sign-on means that when the same account logs in on multiple devices, the new device logs in and the old device is logged out automatically.
